GASOLENE-BURNER FOR INCANDESCENT LIGHTING.

Application filed June 26, 1914. Serial No. 847,424.

To all whom it may concern:

Be it known that I, WILLIAM E. Vonz, a citizen of the United States, anda resident of Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented a certain new and useful Grasolene- Burnerfor Incandescent Lighting, of which the following is a specification.

Objects of the present invention are first to avoid the troubles due tocarbonization and to produce a steady incandescent light from gasolenederived from oils containing a large percentage of compound of thearomatic series, such as asphalt base oils or Texas oils; second, toprovide a vaporizing burner for VVelsbach mantles, or otherincandescents, in which there is a good distribution of heat, and third,to avoid the use of packing in the burner tube and to insure a fullsupply of liquid at the point of vaporization, while at the same timepreventing carbonization in the feed tube and providing against backpressure efiects in the feed tube.

The invention will be claimed at the end hereof, but will be firstdescribed in connection with the accompanying drawings, in which Figure1, is a side View, generally illustrative of one application of a burnerof the invention. Fig. 2, is a side view of a burner embodying featuresof the invention, principally in section. Fig. 3, is a side view takenat right angles to the plane of Fig. 2, and principally in section. Fig.4, is a top or plan view with parts removed. Fig. 5 is a fragmentaryview, drawn to an en larged scale, and Fig. 6, is a horizontal sectionof the vaporizing chamber.

In the drawings 1 is a mixing tube, sometimes also called a Bunsen tube,and it is provided with a jet device 2 arranged to discharge into itslower end.

3, is an interrupted annular vaporizing chamber surrounding the mixingtube and it is interrupted as at 4.

5, is a burner head arranged on the mixing tube and provided withopenings shown as arranged in groups 6 and 7 and adapted to afforddownward sub-jets directed toward the chamber 3 for heating it.

8, is a jet connection from one side of the interruption 4 of thechamber 3 downward to the jet device 20 As shown in the drawings thedescribed parts, along with the braces or stays 9 and 10, make up astructure to which there is applied a wind shield 11 and a feed tube 12.

The feed tube is unobstructed and is pro the feed tube is screwed forthe purpose of cleaning it. The groups of openings 6 and 7 are arrangedon opposite sides of the interruption 4 and this arrangement tends topromote a good distribution of heat and, as shown, there are moreopenings or holes in the group 7 than in the group 6, so that by thisarrangement more heat is applied at the outlet part of the chamber 3than at the inlet part.

The level of liquid or gasolene is free to rise in the tube 12. One wayof accomplish ing this is to connect the tube 12 as by a valved pipe 15with an elevated tank or reservoir 16. There is a series of gauzediaphragms 17 arranged in the tube 12 and spaced apart in the generalpositions indicated in the drawing.

The mode of operation of the burner may be described as follows: Whenthe burner is cold and is to be lighted the level of liquid in the tube12 may rise pretty well up to the upper end of the tube. Heat is thenapplied to the burner as from a torch, with the result that vaporizationis started and the burner lighted. Thereupon the torch is removed.Sub-jets playing downward through the openings of the groups 6 and 7heat the vaporizing chambers with the result that gasolene is vaporizedand passed by way of the connection 8 through the jet device 2 into thetube 1, where it mixes with air and a part of the mixture is burned ontop of the burner head to heat the mantle A, while another and verysmall part of the mixture supplies the sub-jets. The vaporization of theliquid or gasolene in the chamber 3 gives rise to some back pressure inthe tube 12 and the gauze.

may not cause surging of the light, while at c f Gqp es 1 th sra may b6--0bt 1 r this back pressure may cause the level of liquid in the tube12 to descend and it will descend until it reaches one of the gauzes 17.The effect of the gauze 17 is to increase the surface tension of theliquid to such an extent that the back pressure is resisted by thesurface tension of'the liquid in respect to In this way the backpressure the same time heat is not conducted through the tube 12 to anextent or degree suflicient to produce carbonization .and furthermorethere is always sample feed of liquid to the point of vaporization. Itmay be said in [connection with the gauze that it subdivides themeniscus of the liquid as it would exist in the absence of thegauze,producing :a multiplicity of smaller menisci,

thereby increasing thesurface tension so as to oppose back pressure.

What I .claimis:

1. A .gasolene burner tor incandescent lighting comprising thecombination of a mixing tube having a jet device, an interrupted annularvaporizing chamber surrounding the tube, a burner head arranged on thetube and provided underneath with openings affording downward sub-jetsfor the chamber, a jet connection from one side of the interruption ofthe chamber downward to the jet device, an upright gravity feed tubecommunicating with the chamber to the other .side of its interruptionand in which :the liquid level is :free to rise, and a series of spacedgauze .diaphra'gms in the upright portion of said tube which byincreasing fluid tension holds the liquid level :at one or the other-ofsaid gauzes,:substantially .as described.

2'. A gasolene burner for incandescent lighting comprising thecombination of a mixing tube having a jet .device, an interruptedannular vaporizing chamber surrounding the tube, a burner "head arrangedon the tube and provided underneath with openings aiiording down-wardsub-jets for the chamber, balls or like bodies in the chamber, a jetconnection from one side of the interruption of the chamber downward tothe jet device, an upright gravity feed tube communicating with thechamber to the other side of its interruption and in which the liquidlevel is free to rise, and a series of spaced gauze diaphragms in saidupright tube which increase fluid tension and hold the liquid level atone or the other of the gauzes, substantially as described.

3. A gasolene burner for incandescent lighting comprising thecombination of a mixing tube having a jet device, an interrupted annularvaporizing chamber surrounding the .tube, a burner head arranged on thetube and provided underneath with openings affording downward sub-jetsfor the chamber, a jet connection from one side of the interruption ofthe chamber downward .to the jet device, an upright gravity feed tubehaving a lateral jet discharge nozzle communicating with the chamber tothe other side of its interruption and in which tube the liquid level isfree to rise, and a series of spaced gauze diaphragms in said uprighttube which increase fluid tension and tend to hold the liquid level atone or the other of the gauzes, substantially as described.

4:. In a gasolene burner for incandescent lighting the combination of avaporizing chamber, an upright gravity feed tube communicating with thechamber and in which the liquid level is free to rise to the chamher,and ,a series-of spacedgauze diaphragms in said tube which increasefluid tension and hold the liquid level at one or the other of thegauzes, substantially as described.

In testimony whereof I have hereunto signed my name.
